BALL COCK.

Application 11i-ed June 14, 1924. Serial No. 720,015?.I

To all whom t may comem:

Be it known that I, JULIUs PHILLIPS, a citizen of the United States, residing at Trenton, in the count of Mercer and State of New Jersey, have invented new and useful Improvements in Ball Cocks, of Iwhich the following is a s eciication.

This invention re ates to ball cocks and proposes the construction of a float controlled valve particularly adapted for admitting water from a pressure supply to a water-closet flush tank.

The principal object of 'the invention is the promotion of silence in the filling of the tank.

Another object of the invention is to form the valve and iloat control of nonmetallic, non-corrosive, sound dampening substance.

Further objects of the invention w1ll appear as the description proceeds.

Figure 1 is a side view of my* improved ball cock, the operating means being shown in both open and closed positions.

Figure 2 is a vertical sectlon through the valve casing.

Figure 3 is a view similar to Figure 2 taken at a right angle to Figure 2.

Figure 4 is a perspective view of the valve body.

A great deal of thought has been devoted to the endeavor to .solve the problem of making silent the filling and discharge operations of flush tanks such as are connected with modern plumbing systems. The illustrative embodiment of the invention disclosed in the present application relates to the filling mechanism, although the broad principles of the invention l re equally applicable to the discharge means. v

Investigation has shown that the objectionable noise just referred to is caused primarily by the impinging of the supply water under the pressure in the mams against the supply valve and the walls of the valve casing. In the usual metallic construction this noise is communicated to the float through the linkage whlch connects the valve to the fioat, and the latter, being a hollow body, acts as a sound box or resonator augmenting the sound and rendering it disagreeably audible.

The present invention arrlves at a practical solution of this problem by making the valve, the valve casing, linkage between the valve and float, and even the iioat itself, 1f necessary, of sound-dampening substance such as hard rubber.

Referring now in detail to the several figures, the numeral 1 represents the valve caslng formed at its lower end with a threaded nipple or spud 2, the latter being adapted to project through the bottom of the iush tank 3 and to connect with a sou'rce of water under pressure. The valve caslng is provided with a valve seat 4 communicating by way of the conduit 5 with the source of Water supply. A cylindrical valve body 6 is slidably arranged within the valve casing, the lower part of said valve body being formed with a valve head 7 consisting in part of a zone 8 of hard rubber or its equivalent and a terminal portion 9 of soft rubber. portion 9 are integrally formed, their distinguishing characteristics being produced by differences in the process of vulcanization. The terminal portion 9 constitutes the valve proper and co-acts with the valve seat 4. A plug 10'closes the top of the valve casing. Water discharges from the valve casing, when the valve is open, through passages 11 which are downwardly directed to avoid splashing. An elbow 12 is tapped into the side of the valve casing to which is connected the refill tube 12. The parts mentioned, and particularly the valve casing and valve body are made of sound dampening substance such as hard rubber, and as it is upon these parts that The zone 8 and terminal' the entering water impinges, the vibrations ordinarily set'up from this cause are, for the most part, inhibited.

Operating means for the valve body consist of a lever 13, preferably S-shaped and fulcrumed between its ends to the valve casing by means of the pin 14, the latter bein preferably of hard rubber. The lower en of the lever 13 plays within a slot 15 formed in the valve body, and functions to raise or lower the valve. The oat 16 is connected to the lever 13 by means of an arm 17 and said float is angularly adjustable relative to the lever 13 by means of cooperating ratchet faces 1S and 19 formed on the adjacent ends of said lever and arm, which are held together in any position of adjustment by means of the thumb screw 20. The lever 13 and also the arm 17, are

preferably formed of hard rubber or its euivalent so as to dampen the transmlssio'n o such vibrations as are 'not prevented by*EV the construction of the valve body and valve casing. i For Structural reasons 4l have shown the arm 17 as being hollow and pro- Y comprising a valve caslng, a liquld supply vided internally with la metallic stem 2 1, the latter threading into the float 16. Sald stem naturall aects to a slight eatent the eiciency of t e device in so far as its silent o eration is concerned, and may'fbe omitted, i? desired; the rubber portion of the arm 17 being in that case threaded for connection to the float.:

While the float itself may be of metal I have preferred .to makefit, too, of hard rubber, both on account of 1ts non-corrosive property, and Afor the enhancement of the noiselessoperation of the filling mechamsm..Y f Y.

It is to beunderstood that the invention g is not restricted 'to the detailed construction of the Ymechanism but contemplates the broad rinciple of sound inhibition, wherefore I do not restrict myself to the particular constructien here; disclosed, but only by the terms of the claims and the state of the prior art.

Having described by invention what I claim as new and desire to secure by Letters Patent, is

1. A ball cock for water closet Hush tanks comprisin a valve, a float for controlling the operation of said Valve and an operating connection between said float and Valve constituted of rigid members at least one of which is made or' sound dampening substance.
